Stereo to 5.1

Greetings to all. Earlier I had ffdshow audio filters and I just checked the "Apply Dolby Pro Logic II decoding to all stereo sources" box and all my mp3 played at all 6 channels (5.1). Now I'm using LAV filters and my mp3 and all movies with stereo tracks are playing only from left and right speakers. And there are no such options. I've found only "Expand Mono to Stereo" and "Expand 6.1 to 7.1" The mixing tab doesn't help me either. Please help me, thanks in advance.

LAV does not have such functionality (yet).

Big thanks. So I have to go to ffdshow. BTW, can you tell me, why does LAV included? Is it better then ffdshow?

Yes, it is better than ffdshow. But it does not offer much extra non-essential functionality.

ffdshow is included in Full and Mega versions of the pack.

I see. Big thanks.
